Sugammadex represents a paradigm shift in neuromuscular blockade reversal, offering rapid and complete reversal of aminosteroid neuromuscular blocking agents (rocuronium and vecuronium) regardless of block depth. Unlike acetylcholinesterase inhibitors, sugammadex works by direct encapsulation rather than competitive antagonism, providing more predictable and reliable reversal.
Selective relaxant binding agent (modified gamma-cyclodextrin) that encapsulates rocuronium and vecuronium
Moderate blockade (TOF ≥ 2): 2 mg/kg IV; Deep blockade (PTC ≥ 1–2): 4 mg/kg IV
Immediate reversal after rocuronium 1.2 mg/kg: 16 mg/kg IV
No anticholinergic side effects unlike neostigmine; does not require glycopyrrolate co-administration
May reduce hormonal contraceptive efficacy for 7 days post-administration
For cannot-intubate-cannot-ventilate scenarios where succinylcholine was avoided and rocuronium was used, sugammadex 16 mg/kg provides the fastest reversal option. Keep sugammadex immediately accessible in every anesthetizing location.
